The jq-bt Bluetooth driver is essential for devices that require Bluetooth connectivity. Here are some scenarios where the driver plays a critical role:
| Symptom | Possible Fix | |---------|---------------| | hciattach fails | Check baud rate match; ensure no other process uses UART | | No response to AT commands | Loopback test: short TX-RX; verify 3.3V logic level | | Connection drops | Increase UART buffer size; disable flow control mismatch | | Can't enter data mode | Ensure +++ is not followed by CR/LF immediately | | Device not discoverable | Send AT+ROLE=S and AT+RESET | hci_skb_pkt_type(skb) = *skb->
